M76

M76 is another planetary nebula. Although in the case of M57 the nebula was in the shape of a "ring" (actually a sphere), M76 presents a rectangular shape. If you look carefully, it is possible to see a very faint circular nebula about twice the size of the bright rectangular one. It is sometimes also called the "Barbell Nebula".

I took this picture from my driveway.
